TELEPHONE TOLL-INDICATOR.

sPECIFICATIoN forming part of Letters Patent No. 733,494, dated any 14, 1903.

Application filed December 3,1902. Serial No. 133,747. (No model.)

.To a whom it may concern.-

Be it known that I, GEORGE A. LONG, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Telephone Toll- Indicators, of which the following is a specification.

My improvement relates to the class of devices employed in connection with telephones that are used for the purpose of indicating both audibly and visually the fact that certain acts required for the use of the instrument have been performed; and the object of my invention is to provide a device of this class that shall be simple and effective in construction and operation and sightly in appearance and one in which the chances of fraudulentlyindicatingthatthe requirements for the use of the apparatushave been complied with shall be eliminated. A form of device in which these objects may be attained is illustrated in the accompanying drawings, in which- Figure 1 is a view in side elevation of my improved device with the case out in section, the parts being in normal position of rest. Fig. 2 is a like view, but showing the parts in the position with the plunger pushed downward to its farthest limit. Fig. 3 is a front view of the device with the hammer and case removed. Fig. 1 is a top view of the device with the case removed. Fig. 5 is a view in side elevation of the parts from the opposite side of the view of Fig. 1. Fig. 6 is a view in section through the plunger.

' In the accompanying drawings the numeral 1 indicates the base of the apparatus, that is provided with means, as screw holes and screws, for attachment to the back board of a telephone apparatus. A case 2 is attached to the base, preferably removably secured thereto and of proper size and shape to contain the operating mechanism. An opening 3 is formed through the case, into which the face of a registere projects and through which the numerals on the register may be observed. A standard 5 is mounted on the base, preferably formed integral therewith, and the reg ister at is secured to this standard. A projection 6 extends upward from the base and is preferably formed integral therewith.

A gong 7 is secured to the standard 5 and rests as to a portion of its surface close to the projection 6, but not touching the projection when allowed to assume its normal position.

A hammer-lever is pivoted to the side of the standard 5, and this includes a hammerarm 8 and a spring-arm 9. A hammer 10 is borne on the end of the arm in position to strike the gong 7, and'a hammer-spring 11 is attached to the spring-arm at one end and the other end to a muffler-arm 12.

A muffler-lever is mounted on a post 14, rising from the base, and this lever includes the spring-arm 12, a mufller 13, and a muffleractuating arm 15. The muffler 13 in the normal position of the parts rests against the side of the gong 7 and presses it against the projection 6 on the base of the device.

A guide-post 16 is secured to the base, and a pin 17 from the plunger 18 projects into a central opening in this guide. This plunger has a recess 19 located between the pin and the inner wall of the opening in the bottom of the plunger, this recess containing one end of a plunger-spring 20, that surrounds the guide 16 and the pin 17. This plunger has a rigid bearing 21, adapted to press against the edge of the standard 5, and also a cam 22'for actuating the mufller-lever. The plunger also bears a trip 23, having a notch 24, adapted to engage a trip-pin 25 on the hammer 10. This tripis pivoted to the plunger, and a tripspring 26 thrusts against the edge of the trip, forcing its free end outward 'from the plunger. The plunger also bears a register-operating pin 27, which engages a slot in the register-arm 28, secured to the shaft 29 of the register. The register is of the kind known as a ratchet-operated register of ordinary construction, and further description is deemed unnecessary herein.

In the operation of the device the parts are in the relative position shown in Fig. 1, with the trip 23 in engagement with the pin 25 and the muffler 13 resting against the gong and clamping the latter against the projection 6 under the pull of thespring 11. The plunger being pushed down, the engagement of the trip with the trip-pin 25 forces the'hammer away from the gong, this movement carrying the free end of the trip away from the plun-' ger. A stop 30 on'the back of the trip engages the side of the plungerand prevents forward movement of the free end of the trip. Further downward movement disengages the trip from the trip-pin 25, and the hammer is forced against the gong by the pull of the spring 6. Just before the hammer is freed from engagement with the trip the cam 22 on the lower end of the plunger engages the muffler-arm 15, swinging the inuffier-lever and throwing the muffler away from the gong. The muffler is held away from the gong until the upward movement of the plunger releases the lever, when the muffler is again thrown against the gong, clamping it between the muffler and the projection 6 from the base. Further upward movement of the plunger again causes the trip to engage the trip-pin 25, thus resetting the parts. The downward movement of the plunger through the engagement of the pin 27 with the slot in the register arm moves the register forward a unit space, the return movement of the plunger carrying the arm backward in position to again operate the register.

It will be noted that the muffler in the normal position of the parts clamps the gong between the muffler and the projection from the base, and it is therefore impossible to sound the gong, as by a sharp blow delivered 011 the outside of the case iuclosing the mechanism, as is possible in prior devices where the gong is free to vibrate at all times. It will be noted that the muffler is thrown away from the gong at the time the hammer is released to strike it, and the vibrations of the gong may be continued for any interval desired by holding the plunger depressed. Immediately upon releasing pressure on the plunger the muffler will be thrown against the gong and the vibration thereof stopped.

It is obvious that the details of construction of the device may be varied to a considerable extent and yet embody the main features of the invention, and I do not desire to limit myself to the exact form of construction and mode of operation herein illustrated and described.

What I claim as my invention, and desire to secure by Letters Patent, is-
